Ive found that unless you're really gunning for the gear they sell you end up getting better gear from quest rewards. Ive yet to have purchased anything with those tokens. I think they should make the gear useable as templates for appearance changes but you cant even do that with them.

If the gear was worth it like the jax trust stuff then it would be more than worth it to save them. Unfortunately the gear is not worth the time it would take to gain enough tokens to get the gear they offer.
